STARTING DEVICE.

osnaesr I r I I Application filed August To all whom it may concern: I I

a citizen of the United States,and-a resi the county of Milamhave invented a new and Improved Starting Device, of which the'following isa-full, clear, and exact de scription.

The invention relates to starting devices particularly adaptable for internal combns tion engines,,-and has for an object to provide a device for starting. an engine by means of energy stored up by the said engine when previously in operation.

' For the'purpose mentioned use is made of a pinion for rigid attachment to one end of the shaft of an engine, an internally toothed rack operatively mounted on the pinion and provided with an extendedrod in engage ment with a spring, means on the rack for holding the plnlon in an operative position relative to the rack, and means engag-'.

'- ingthe'rack for connecting the rack and pinion, to release the said spring after the same has been substantially compressed.

Reference is to be had to the accom anying drawings constituting a part 0 this specification, in which similar characters of reference denote corresponding parts in all eviews, and in which- Figure 11s a partlal plan View of an automobile equipped with my device; Fig. 2'

is 'a sectional Fig. 1; F ig. the line 33 in Fig. 2; and Fig. 4:- is a fragmentary' plan view of the'cut-out clutch of my device.

Referring more particularly to the various views, I provide a inion 10, rigidly mounted on a shaft 11, 0 an internal combustion engine mounted in an automobile 12, and constituting the driving medium for theautomobile. A rack 13, having internal teeth 14, partially encircling the inner .periphery of the rack, is provided with an extended rod 15'? on'which a spiral spring ,16, is .operatively disposed. A portion 17 of the rack 13, on the mner periphery thereof, is left blank or smooth and toothless, as will be easily seen in Fig. 2. A plurality of j transversely extending supports 18 are secured to the rack 13, and consist of two loops 19, having a depending intermediate portion 20, to which is secured a. longitudiview taken on the line 2- -2 in Specification of Letters Patent.

the same ping. Now supposing that the engine has started;-thepinion 10 carried by the shaft shown in dotted lines in 3 is a sectional view taken on tween the teeth 14 and the Patented Feb. 21 1911.

atone end with oppositely disposed similar rollers 22. On the frame23 of the automo-' bile 12, a rod 24 is mounted to turn, and

ment with the rack 13. 1

It will be understood, that in" the operation of my device the energy for starting the engine is stored up by the engine while Was-in operation previous to stopterminatesin an offset end 25 for engage- 11 will rotate and consequently the rack 13 will operate on the pinion 10 until the blank portion 17, adjacent the starting point, is reached. .As the blank portion 17 approaches the pinion, the same, position of the rackand pinion when the blank portion is reached, is substantially Fig. 2. It will now be seen that owing to the smooth surface of the portion 17, the rack 13 will cease to operate on the pinion 10,and it will be further noticed that during the travel of the rack over the pinion, the spring 16 has been gradually compressed. Now, if the en-' gine is stopped and it-is desired to restart the same, the lever rod 24 is operated to move-the end 25 against the rack 13. This movement of the lever rod causes the rack to exert apressure against the pinion, and the said pinion turning on the rollers 22 per, mits the rack to move, and the pinion 13 is again engaged-by the first of the teeth 14 on the rack. At the moment of contact bethe rollers 22 engage' acting as guides, and the relative.

pinion 10, the

energy collected in the spring. 16 is released,

owing to the longitudinal pressure of 'the rack against the pinion being removed, and the rack 13 operates over the pinion 10,

which rotates and in turn rotates the-shaft 11, thus workingthe pistons of the engine and operating the necessary engine parts. to start the same. After the engine is started andis operating in the regular'mannor, the rack 13 moves over the pinion as previously mentioned, and the spring 16 is again compressed until the smooth or blank portion 17 engages the pinion, thus stopping the movement of the rack.

and my starting device, the starting device .105 By providing a clutch member 26 forconnection between the shaft of the engine can be at any moment disconnected from theshaft, thus enabling the operator to crank the engine in the usual manner.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent I '1. A starting device comprising a pinion mounted to turn with the shaft of an engine,

2. A starting device comprising a pinion mounted to turn in the shaft of an engine,

a rack provided with a blank portion and engaging the pinion to be operated thereby to compress a spring, a plurality of trans versely extending supports on the pinion, a roller member secured to-the supports, roll-1 ers on the roller member and adapted to be engaged by the pinion when the same moves onto the said blank "portion of the rack and a lever for engagement with the said rack to release the said spring to operate the pinion after the same has moved onto the blank portion of the said rack; n a

In testimony whereof I have signed my name to this specification'in the presence of two subscribing Witnesses.
